Notes for Instrumentation Service
 On yx1x systems, if conflicting BIOS settings exist when configuring BIOS setup options through
Server Administrator, the update attempt may fail at system reboot and none of the BIOS setup
options may be updated.
For example, when you configure Embedded SATA Controller to RAID and Boot Mode to UEFI
simultaneously (UEFI does not support RAID option), this conflict prevents any BIOS configuration
to be updated (at system reboot).
 On certain systems, user-defined thresholds set under Server Administrator become the default
thresholds after uninstalling Server Administrator.
After you change the threshold value of a probe on certain systems running Server Administrator
and then uninstall the application, the changed threshold value becomes the default threshold
value.
 While modifying the warning threshold settings, the values are stored in the firmware as discrete
integer values and scaled for display. If the modified value is not a discrete integer, it may
change when saved.
 Fan redundancy can have the following states:
- Fully Redundant: The sensors display this status if all the fans in the system are present
and are in a non-failure state.
OR
-
Redundancy Lost: The sensors display this status whenever any system fan fails or
is removed from the chassis.
 If a system with memory redundancy enabled enters a "redundancy lost" state, it may not be clear
which memory module caused it. If you cannot determine which Dual In-line Memory Module
(DIMM) to replace, see the "switch to spare memory detected" log entry in the ESM system log to
find the memory module that failed.
 If you run Server Administrator while the system is in "OS Install Mode", it may report the memory
incorrectly. To avoid this issue, you must disable "OS Install Mode" before running the application.
 If you have to uninstall and reinstall the operating system SNMP service, then reinstall Server
Administrator, so that the Server Administrator SNMP agents are registered with the operating
system SNMP agent.
 Server Administrator Device Drivers for Linux
Server Administrator includes two device drivers for Linux: Dell Systems Management Base Driver
(dcdbas) and Dell BIOS Update Driver(dell_rbu). Server Administrator uses these drivers to
perform its systems management functions. Depending on the system, the application loads one or
both of these drivers. These drivers have been released as open source under the GNU General
Public License v2.0. They are available in Linux kernels from kernel.org starting with kernel
2.6.14.
